Lavry Blue vs. Mytek AB listening test (also Lavry vs. Apogee)

[Ruphus]

Teacher, you´re wellcome :O), and yep, I thought the same; DAC1 especially for rap & techno demands.

Matous,

The device you show seems the one I meant with having that
" ... a very popular quality passive attentuator with a gazillion steps."

and

"... a simple controller with that attentuator build in. However it seems to be made for prosumer and has only RCA jacks."

Looks like they got XLR connex available now.

Ivo,

Meanwhile I got reply from SPL about the coming stereo controller. They havn´t measuered it yet, cause of delay in manufactory and because they measure only on the serial product ( no-brainer ).

But it is supposed to be of similar design as their souround controller which I believe is being regarded as pretty good.

I wanted to know which sections would be active. They said only the inevitable like summing stages ( as passives were to give impedance problems the more channels involved ) and the output drivers.

Just asked them if they could imagine to include one pair of inputs splitted of which the one pair would be driven by the main pot and the other pair just been routed out ( for outboard feeding ), so that you could either monitor or feed outboard through your best pair of D/A without having to plug around each time.

James,

The LA Audio seems to have great routing options. Can you tell us more to which controllers you compared it to? And maybe what D/A you were using?

Ruphus, thanks. It is funny that a simple decreasing of volume requires $ 500 unit (if cheap).
I asked an audiophile electronic expert friend to construct a simple transparent attenuator for me. I do not need anything else than just one knob . Let us see ...

Not really. What djs writes (not sufficient volume control) scares me. I absolutely do not feel like moving with some screws within Lavry. With such a rough action (decreasing the output volume), how can you be sure, that your L and R remain in exactly the same level ??

Any decent analyzer software will display .1 db increments.

What you do is feed D/A outputs back into the inputs and twist the screws while watching the meters or db level in the daw. Just make sure your monitors are off or do something so it doesn't feedback.

Returning quickly

This is not normal at all. It sounds like you've got a broken pot on the ATTY. I've pointed this thread out to Peter Montessi owner of A-Designs, and he would like to replace your broken unit asap (providing your dealer cannot provide immediate support). Here is their contact:

Hope this helps.

Like routing the receivings tracks output to other channels than the masters.

A totally passive level control can be built using a pair of Sowter attenuator transformers. You literally just put a pair in a box and wire them up with some i/o connectors, and the transformer tap wires to a pot.

Check out the Attenuators page at Sowter Transformers

There's a cool picture at the bottom.

Also, NHT Pro makes a cheap passive attenuator that sounded good when I heard it once in a very nice demo room.

nathan, i had these same problems with mine (useing the lavry converters), sent it back to atty, they tested it, and they said it was working fine. they sent me a second unit, which when used in tandom with the first gave better results. all of these problems were drastically lessened with the use of a second unit. my thoughts are that the signal is too hot for 1 atty to handel, and the crackling, and uneven ballance are things that are only happining at the low volume position (going from 0-1 or 2 on the dial). the problem goes away at higher knob settings. if the incoming signal is lowered the atty responds much better. unfortunatley, it still lacks the attenuation most people are probably used to (and should expect with a good monitoring attenuator). the units work great for mic attenuators and stuff like that, but for monitoring attenuation, not so much. the customer service at a-designs is some of the best i've ever encountered though. if these problems are also happining at higher levels, the unit might very well have a problem, and a-designs will take care of any problem you may have.

i just wanted to mention this stuff so people dont start sending atty's in left and right to get fixed, when there may not be anything broken.

i think some sort of 20db pad switch would be a fabulous addition to the box.

It seems so. The Lavry output is really hot and I could use just very minimum volume level in Atty. The stereo balance was very unbalanced (always pointed to one side). Peter Montessi suggested using two Atty units for making them usable with Lavry. I will try them soon .

Yes, indeed I have never experienced such a sincere care from any manufacturer so far

Glad to hear it worked out... I know A-Designs works their tail off to make customers happy.

I've had the older unbalanced version, used it for Hi-Fi.
Had to put it in a metal box, solder a couple of cables, spray the box with a nice blue color, add a chicken knob. No big deal.

we intensivly compared lavry blue da with the apogee 16 da at our german lavry dealer Lavry Engineering
and we will go for 24 lavry da s now. thjats was a hard decission but the result is clearly better.

AD/DA... sorry that i must say but you post in nearly every topic advertisement for (your?) shop....
I doesn't think that's the purpose of this forum. If you want to make advertisement add it at your signature and not at every post.
Don't only hype products what you sell at your shop, that just makes your opinion less trusted.

Btw. the topic was like 4 year old...
